Continuity mistake: In the sequence of the laser rays, Agent 99 comes out of the sewer with her shoes on. Never the less, when she begins to do her stunt to cross without touching the lasers, she has them off. Then when she has crossed, she has them on again, but we never actually see her take them off or carry them while she is crossing.
Continuity mistake: The skydiving sequence between Smart, 99 and Dalip is a mess of continuity errors; obviously the product of multiple takes/jumps. It begins over fields with no clouds below them, then on each subsequent shift in camera angles the area below them is either completely cloudy or clear. Then they fall through the clouds (which were not there originally). After coming through the bottom of the clouds the scene continues to shift between them falling to a cloudless background and a cloudy one.
Continuity mistake: In the plane's bathroom, when Max is about to be sucked out of the plane, he has his swiss army knife in his mouth. But in the next shot, the bird's eye view of him being sucked out, his swiss army knife vanishes. It's foreseeable that in between shots Max uses his hands to pocket the knife but both the speed at which he would have to do it and the fact his hands are still clenched in the same position they were in the previous shot makes it very unlikely.
Continuity mistake: Prior to Max being sucked out of the plane, he holds his knife in his mouth. When he is ejected, he is still carrying it in his mouth. He screams, however, and the knife should have fallen. But Max supposedly still has the knife later in the movie. (He tells 99 to take his knife from his pocket.) It is possible he pocketed it, but unlikely, as stated in a previous mistake.
Continuity mistake: When Max and the Chief are in the plane, the banner is attached to the cable at the end where it says "IT." When they go low and Max is by the yellow truck, the banner is now attached at the opposite end, where is says "suicide." In later shots it's attached back the other way.
Continuity mistake: When Agent 23 kidnaps Agent 99 at the end, he puts her in the car, he then gets in and drives away. He is wearing a suit jacket and tie but the next interior shot shows him without the jacket or tie, his shirt undone, and sleeves rolled up. Impossible to do at any time while driving, let alone in a car chase.
Continuity mistake: When Max is entering CONTROL through all of the doors and a paper gets caught in one, the paper is moved out of frame as a whole piece of paper. When the camera moves up, the paper is now ripped in half. Even though you hear a ripping noise afterwards, enough time has not passed for the paper to be ripped and it is one continuous shot.
